IMPROVEENT EN SIGNALHLNTERNS.

Specilication forming part of Letters Patent No. P33323, dated August26, 1873 application led September 17, 1872. i

To all whom it may concern:

Be it known that I, HENRY B. FERNALD, of the city and county ofWashington and District of Columbia, have invented certain new anduseful Improvements in Signal-Lanterns 5 and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings forming jpart of thisspecification, in which- Y Figure 1 isa side elevation of the apparatuscomplete. Fig. 2 is a vertical section in the line y y of Fig.` 3; andFig. 3 is a horizontal section in the line so x, Fig. 1.

Similar letters in the accompanying drawings denote the same parts.

This invention has for its object to improve the construction of signal-lanterns having glasses ofvarious hues for railroads, steamqboats,Svc., in such mannerv as to make the lantern rotatable within its case,in order that it may emit light of different colors at dilerent times.To this end the invention consists in the combination, with aninclosing-case, of

a lantern having a part projecting to or beyoud the bottom lof the case,which part forms means for conveniently supporting the lamp and turningthe lantern, as I will now proceed to describe.V

In the drawings, A are the variously-shaded glasses of the lantern,attached thereto in the usual manner; and B is the inclosing-case, openon two sides. From the top of the lantern a dome, C, projects above thetop of the case, and from the bottom of the lantern a ring, D, extendsdownward within the ring E at the lower end of the case. The ring Dterminates a little short of the bottom of the foot F of the lantern.The lamp is inserted within the ring D, and supported with springsattached to the lantern, and resting on the iiange I or" the ring, asshown in Fig. 2. G are wires extending from one part of the case to theother across the open sides of the same, to protect the lantern. Theannular top E of the case that incloses the dome C is removable,havinggrooves in its outer edge, by means of which it can be slippedbetween ears h attached to the sides of the case, after which, byturning the ring H, its edge passes under the ears h, and it is heldthereby.

The part H can be removed from the case by turning it backward till itsslots coincide with the ears h, when it can be lifted clear of them. Thelantern can then be taken out of the case or placed in it.

When the apparatus is carried on the arm the lantern can be turned byapplying the hand to the ringD; and in this respect my invention dilersfrom other rotatinglanterns, which are turned by applying the hand tothe body of the lantern through the'open sides of the case.

Lu'gs extending downward from the lower corners of the lantern enterholes'made for their reception in the case, and so serve to steady thelantern. When the latter is to be revolved it has to be lifted, so thatthe lugs are clear of the holes.

When the lantern is elevated at the top of a post it can be turned byapplying suitable means to the ring D.

Having thus described my invention, what I claim is 1. The lantern A,having the ring D extending vertically downward from its lower end, andprovided on its inside with the flange I for supporting the lamp, incombination with the case B, having the ring E extending downward fromits lower end, and inclosing and protecting the ring D and the lamp, allthese parts ,being arranged substantially as described.

2. The case B, combined with the detachable top H, in the mannerspecilied.
